The plight of the club was so extreme that Sir Alex Ferguson was forced to bring Paul Scholes out of retirement in an effort to beef up his midfield.
The worries began early in the season when the club revealed that Tom Cleverley would be out until February at the earliest as he copes with an ankle injury.
Darren Fletcher was unveiled as another long-term injury in December, when it came out that the Scot was taking time off from the game to battle a stomach illness he had endured for the past four years.
Ki is a player that has featured very consistently for Celtic this season, starting in 15 of his 20 Scottish Premier League appearances.
The South Korean also started seven of the Hoops’ Europa League fixtures this campaign and has been sounded out as a major talent.
If the Red Devils weren’t enduring such troubled times in regards to injuries, Ki’s move may not even be discussed, however the problems exist and he may very well get his shot at the big time.
The central midfielder is currently valued at around £7m and would have Korean Republic legend compatriot Park Ji-Sung to welcome him to Old Trafford.
The 22 year-old had an impressive 2011, in which he was named South Korean player of the year.
Despite his age, Ki has already accumulated 44 international caps for his national team and carries experience beyond his years.
